Patented Feb. 2S, 1911.

Application filed January 26, 1909. Serial No. 474,298.

To all whom it may concern:

Be it known that I, VILLIAM J. MAiN, a citizen of the United States, residing atlVestport, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Apparatus for Registering Sheets, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in apparatus for registering sheets.

In registering sheets, in order to enable subsequent operations, such as printing, folding, etc., to be performed upon them, 1t is customary, in certain classes of work, to register the sheet by gages which operate on the front or side edge of the sheet or both edges. ln certain other classes of work, the register is effected by means of register marks on the sheets, these marks being brought into register with registering devices mounted on the sheet support. rFhe register' obtained by the use of registering devices and marks upon the sheet is, as a rule, much more accurate than that which can be obtained from what may be termed edge register, but it is much slower and requires careful and accurate placing of the sheets in position by the operator. As a rule, the register marks on the sheet are as widely separated as possible, being usually located on opposite edges or ends of the sheet. Vhei'e the sheets are largethis requires the operator, in registering, to look at two points in succession which requires time and reduces the speed of the feeding operation. In some cases, also, where very large sheets are to be fed, two operators, one for each register mark, are required.

The object of the invention is to produce an improved registering apparatus which enables the registration of sheets to be effected by observing the position of the image of a sheet, the image being refiected upon a suitable receiver.

lith this and other objects not specifically referred to in view, the invention consists in certain constructions and in certain parts, improvements and combinations, as will be hereinafter fully described and then specifically pointed out.

In the accompanying drawings-Figure 1 is a. side elevation, partly in section, of a construction embodying the invention. Fig. 2 is a plan view. F ig. 3 is a section on the line 3 3 of Fig. 1. Fig. l is a detail sho-wing a modified form of part of the apparatus. Fig. 5 is a plan view of the receiver box.

Referring to the drawings which illustrate one embodiment of the invention, 1 indicates a sheet support which may be of any suitable character, such, for instance, as a table.

The sheet to be registered is indicated at 2, the sheet, after the registration is effected, being taken by any suitable agency, such, for instance, as grippers 3, diagrammatically indicated as being mounted on a cylinder el, also diagrammatically indicated.

Constructions embodying the invention will include a receiver upon which the image of the sheet, or certain parts of it, is thrown. This receiver may be of any suitable construction, and may be mounted in varying ways. In the particular construction shown, this receiver comprises a ground glass plate 5 mounted in a receiver box 6. Constructions embodying the invention will also include suitable image reflecting means, and, in the best constructions, these reflecting means will be such as to throw upon the receiver independent images of different parts of the sheet. The image reflecting means illustrated reflects the images of parts of the ends of the sheet, that for one end including an angularly disposed mirror, as 7, mounted upon a backing plate 8, this plate being mounted on a casting 9. This casting, in the particular construction illustrated, affords a bearing for a. tube consisting of two sections, 10, 11.

Coperating with the mirror 7 is another mirror 12, this mirror being shown as supported on a bracket 13 mounted on a shaft 14 journaled in bearings in the receiver box. In the best constructions, and as shown, this mirror 12, when employed, will be adjustable so as to properly throw the image reflected upon it by the mirror 7 on the receiver. The part 10 of the tube, when employed, should be so arranged as to be directly over that part of the sheet the image of which is to be refiected on the receiver. l these hangers being in turn supported by rEhe part of the sheet t-he image of which is thus refiected may bear register marks, or, under some circumstances, a portion of a design upon the sheet reflected may be utilized for registering purposes. In the best constructions, means will be employed for strongly lighting that part of the sheet the image of which is to be thus reflected. As shown, one side of the part l0 of the tube is cut away and there is secured to it a refiector l5 which contains an electric lamp 1G, this lamp being supported in a holder 17.

rfhe apparatus may include devices for magnifying the reflected image. Vhile the particular construction of these devices, when employed, may vary, as shown they comprise a magnifying lens, as 20, mounted in a lens tube 2l adjustably secured in the part 1l of the tube 10, 1l, by means of a nut and clamp screw QQ, the part 1l being provided with a slot Q3 to enable the adjustment to be effected. The means employed for reflecting the other image is a duplicate of that already described, that is to say, it includes an angularly disposed mirror Q-.t mounted upon a backing plate 25 supported in a bearing QG which also supports a tube comprising two parts 27, 28. The mirror cooperating with the mirror 24 is shown in dotted lines Q9 in Fig. l, and a magnifying lens 30 is shown mounted in an adjustable lens tube 31 located in the part 2S of the tube. A lighting apparatus comprising a light 32 and a reflector 33 is also employed. The mirror 99 is shown as mounted on a shaft 3l; mounted in the receiver boX.

In the best constructions and as shown, the mirrors l2 and 29 will be made adjustable to properly position images upon the receiver. Tilhile this may be accomplished in various ways, in the construction illustrated, each of the shafts llt and 34 is provided with a graduated adjusting plate 35 slotted at 3G and held in place by a thumb screw 37. A suitable pointer, as 3S, may be provided which coperates with the graduation marks on the plate.

In the best constructions, and as shown,

4the apparatus will be adjustable for us-e with sheets of different lengths, and, furthermore, the construction will be such that the position of the receiver may be adjusted to suit the position of the operator. As illustrated, the receiver box is provided withl bearings 39 which receive the tubes ll and QS, these bearings being provided with holding screws 40. T he bearings 39 can be elongated so as to permit the tubes to be moved therein, thereby increasing the length of the apparatus.

The apparatus may be supported in any suitable way. As shown, the bearings 9 and 2G have strap hangers .t1 connected thereto,

rods 43 located over the sheet support and mounted in any suitable way on the machine fran e. If desired, a screen, as stat, may be mounted in the receiver box to prevent the light reflected through either the tube l1 or 2S from interfering with the light reflected through the other tube. It will of course be understood that the reflecting means employed should, to obtain the best results, be so arranged as to bring into relatively close relation independent reflected images of relatively widely separated parts of the sheet. l `urther while excellent results may be obtained in most cases b v reflecting independent images of two widely separated parts of the sheet, the apparatus may be constructed to refiect more than two parts, if desired.

rhe registration of the sheet may be determined in various ways. For instance, the receiver may be provided with gage marks, as 45, l-t-(S, the apparatus being so adjusted that when the reflection of the gage marks on the sheet, or parts of the design on the sheet, are in proper relation with the marks t-, 4G, the operator will know that the sheet is in register. Another way for determining the registration of the sheet is to provide the tubes l0 and 2T with crossed-wires, as -l-T, as shown in the detail, Fig. lt, the sheet being registered by so positioning it that the reflection of the registry marks thereon will fall in proper relation to the reflection of the crossed wires. Various other ays which will suggest themselves to those skilled in the art may be employed to determine when the sheets are in register.

The operation of the apparatus willbe obvious from the description heretofore given. By properly locating the receiver with respect to the line of vision of the operator, the position of the sheets can be readily determined by him ata single glance, as the registry marks should be reflected close together upon the receiver.

Changes and variations may be made in the specific construction by which the invention is carried into effect. The invention is not, therefore7 to be confined to the particular construction herein shown and described.
